YH-69 is used successfully in the rubber industry as a dual functional organic
poly sulfur silane coupling agent.
YH-69 can be used in the vulcanized rubber system with fillers such as silica,
fiberglass, talc powder, mica powder and clay as reinforcing agent. It can improve the reinforcing properties of fillers and rubber abrasive resistance properties.It is suitable
to be used as rubber additive---vulcanizing agent and activator in polymers such as
NR, IR, SBR, BR, NBR and EPDM.
In the process of vulcanization, the crosslinking rate of poly-sulfur alkyl is the same
as deoxidizing rate of sulfur, so it act to resist deoxidization of vulcanization, and then
improve dynamic bending properties such as heat build up and cracks expansion .The
four sulfur atoms can act as activator for vulcanization.
In dynamic and static conditions, It is used for producing these rubber products: tire,
hose, rubber roll, belting, cable, footwear and mechanical founding products. It can
improve abrasive resistance, cutting resistance and pressure resistance, reduce
hysteresis loss and hygroscopicity, improve mechanical and adhesive properties, and
increase thermal ageing performance, modulus and flex life.
Add sulfur-silane coupling agent in the industry of rubber tire, its not only debase
the risk of puncture as temperature too high running on the high speed road or long
time, but also reduce roll resistance of tire, then reduce the consume of gasoline, the
emissions quantity of CO₂ as to accord the environmental protection of carbon
reduction.
